Do HVAC contractors need a license in Indiana?
How Indiana licenses HVAC work
There is no statewide HVAC contractor license that we could find; cities or counties license HVAC work.
Local rules: The Indiana Professional Licensing Agency's list of licensed professions includes plumbing but shows no HVAC, heating, air conditioning, refrigeration or mechanical contractor category, so we could not find a statewide HVAC contractor license and we believe any licensing is set by individual cities and counties. We could not read the Indianapolis, Evansville or Fort Wayne licensing pages (the city sites returned no usable content or blocked access), so we could not confirm any specific local HVAC license, its name, or its requirements.
Call your city or county building department and ask whether HVAC contractors must be licensed or registered locally and whether a permit is required, then ask the contractor for that local license or registration number and confirm it with the department.
Federal rule: in every state, technicians who handle refrigerant must hold EPA Section 608 certification, whatever the state or city requires.
We could not confirm every detail from Indiana’s own sources, so treat this as a starting point and check with the agency.
Sources: in.gov. Checked October 2026 from official sources. This is not legal advice.
Before you hire
Ask for the license number and check it on the official lookup where one exists. Ask for proof of insurance and a written, itemized estimate, and ask who pulls the permit if the job needs one – a new furnace, heat pump or air conditioner usually does.

No heat in freezing weather, or no cooling in dangerous heat? Call a company from the list that says it takes emergency calls – a form is not fast enough. If you smell gas or a carbon monoxide alarm sounds, leave first and call 911 or your gas utility from outside.
